Acid Red 128, supplied by Sparrowings International, is an acid dye with CAS number 6548-30-7, also known as Acid Red S2B. Its molecular formula is C37H28N4Na2O12S3, and it is registered under EINECS number 229-469-1. This powder-form dye originates from Gujarat, India, and is primarily used in textile applications.
The dye’s chemical structure includes multiple sulfonate groups, which provide excellent water solubility and strong affinity for protein fibres such as wool and silk. Standard for this class, Acid Red 128 offers good wash fastness and moderate lightfastness, typically rated 4 on the ISO 105-B02 scale. It is often used in combination with other acid dyes to achieve specific shades.
Textile manufacturers source Acid Red 128 for its ability to produce bright, consistent red hues on natural and synthetic fibres. Buyers should verify dye compatibility with their fibre types and processing conditions. Trade terms for this product usually include FOB Ahmedabad, with packaging in 25 kg multi-wall paper bags with polyethylene inner liners.

Logistics for Acid Red 128 from Gujarat typically involve FOB Ahmedabad incoterms, with lead times of 4-6 weeks for full container loads.
